.MILK PURIFYING :AND HOM OGENIZING MACHINE.

Specification of Letters Patent.

Application filed March 11', 1910 Patented Mar. 28, 1911. erial No. 548,536.

To all whom it may concern:

Be it known that I, HENRY H. STfissY, a citizen of the United States, and a resident of Sioux City, Leeds Station, in the county .of Woodbury and State of Iowa, have in ventedv a new and Improved Milk Purifying and Homogenizing Machine, of which the following is a full, clear, and eXact descri tion.

T is invention relates to milk purifying 2tI1d'h0II10g8I11ZlIlg maclnnes, and has referonce more particularly to a machine of this class in which milk is passed centrifugally from a receptacle, through a plurality of openings, into an irregularly-shaped conduit, which assists in the homogenizing of themilk,.tl1e conduit having a plurality of escape outlets.

The object of the invention is to provide a simple and eflicient machine of the class described, by means of which milk can be ren dered stable, and insensitive to sourcing causes, by means of which impurities can be removed. from the milk, and in which the globules of butter-fat are broken up. and thoroughly disseminated. throughout the milk.,

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure l is a partial longitudinal section showing certain of the elements of an embodiment of'my invention; Fig. 2 is a longitudinal section of a part of the device; and

Fig. 3 is an enlarged, fragmentary section showing a detail.

Before proceeding to a more detailed'explanation of my invention, it should be clearly understood that the present form of the device constitutes an improvement upon the milk purifying and homogenizing machine shown in In United States Patent N 0. 900,446, dated. provement resides mainly in providing the irregularly-shaped conduit with a. plurality of escape outlets, and also in forming the receptaclewith -anumber of Jo'penings through which the milk can escape 'centrifu-- gally into the irregularly-shaped conduit.

fore arranged to ctober 6, 1908. The im- These openings are arranged at different heights in the receptacle, and permit the milk to escape at different levels, thereby facilitating and increasing the rapidity of operation of the machine. ing action is. effected by the hurling of the milk spray against the irregular wall ofthe conduit, whereby the "butter-globules are broken up and comminuted.

iVhile I have shown in the accompanying drawings a form of the machine in which the members forming the irregularly-shaped conduit are rigidly connected, and are thererotate together,v this departure'from the earlier form ofmy invention is optional, and-if so desired, one of the members. may be fiXed, z". 6., that forming the receptacle can rotate as is disclosed in. the patent above referred to. The plurality of openings would however, be employed in the latter case tov permit the milk to passfrom the receptacle into the irregularly-shaped conduit, and to escape from the latter,.these openings constituting escape nozzles.

Referring more particularly to the draw-. ings, I employ a casing 10, having abottom 11, which may form part of the frame of the machine (not shown). The casing has a top 12 provided with a threaded flange engaging at the corresponding threaded rim of the casing. The bottom 11 may have a similar, upwardly disposed flange, which receives the IOWGF'ITIH of the casing. The top has a substantially central opening 13 through which extends a tubular member 14, having at the top a funnel-shaped extension 15. The tubular member 14: serves for the introduction of the milk into the machine. and has a threaded collar 16 by means of which it can be held in position at the top, and which permits of its adjustment. A shaft 17 extends through the bottomv of the casing, and carries a cylindrical, fluid receptacle 18, located within the casing, and preferably concentric therewith. The receptacle is outwardly tapered at the inside, and

provided with rounded, spiral grooves 19, which have associated therewith, threaded openings 20 through the wall of the receptacle. Plugs 21 correspondingly threaded,

are fitted'into the openings 20, and have passages 22 therethrough. The plugs have the inner faces rounded to correspond to the curvature of the grooves, as is shown most clearly in Fig. 3, and with the groove form The homogeniz- It is threaded said members having pluralities'of openings therethrough, and means for operating said receptacle member to eject milk therein,

rotatable receptacle having a plurality of.

- openings through the wall thereof, a member encompassing said receptacle and spaced from said receptacle, and means for rotating said receptacle, said member presenting a homogenizing surface.

'9. In a machine of the class described, a rotatable, cylindrical rece' tacle' having grooves'formed at the sinsi e thereof, and having openings through the wall thereof, communicating with said grooves, a cylindrical member encompassing said receptacle, said member at the inner side, being provided with grooves, and having openings through the wall thereof, communicating with said grooves, said openings of said receptacle being positioned between adjacent grooves of said member.

,mcating, with said spira 10. In a machine of the class described, a rotatable, cylindrical receptacle having a, spiral groove at the inside thereof, and openings through the wall thereof, communicating with said spiral groove, a cover n on sa1d receptacle, and havin a downwar yextending cylindrical mem r encompassin said receptacle and-spaced therefrom, sai cylindrical member having a spiral oove at the inside thereof and provide with openingsthrough the wall thereof, commuencompassing said receptac e and said member and hav: a shelf adapted to receive fluid escaping rough said openings of said receptacle and said cylindrical member, and means for rotatin said receptacle.

In testimony w ereof I'have signed my oove, a casing name to this specification in the presence of two subscribing witnesses. HENRY H. STUSSYL Witnesses:
